China is now a member of world trade organization . As a member of TO , China will have to make some changes in its economic policies so that it can follow the routines practiced by other TO members . Is it fair to China , do you think ?   It's a hard question , but I'm sure the reexamination of China's economic policies in the past may lead us to a right answer to the question . After the establishment of new China , our government employed numerous economics policies to stimulate the growth of China's economy . These policies , however , favored our domestic enterprises and protected them from international competition and these policies have contributed a lot to the rapid growth of both China economy and our domestic enterprises . After China's entry into TO , Chinese domestic enterprises will have to compete with their foreign counterparts . This new situation entails some changes of Chinese economic policies . These changes will spur Chinese enterprises to strengthen their competitiveness in the long run .   We can infer that the non-discrimination principle is one of the most important principles of TO agreement . This principle requires equal treatment of domestic and foreign enterprise . Does the principle also apply to domestic enterprise of different ownerships ?   Yes , it does . Domestic enterprises of different ownerships enjoy equal rights for the non-discrimination principle grants equal rights to enterprises , regardless of their nationality and ownership . I have found that although changes of China's economic policies are numerous , these changes are largely based on the most important economic principle ot TO agreement-non-discrimination principle . Such an understanding of principle of the changes may help us not only to have a good insight into the changes but also to foresee the tendency of the new changes of China's economic policies .
